placing origin at end of Bezier Curve
Here are a few ways to do it:

Go to Preferences &gt; Add-ons and search for &quot;Curve Tools&quot; and activate the Add Curve: Curve Tools add-on by checking the box next to it. In the 3D Viewport press N to extent the Tool Shelf and click the Edit tab. Then go to Curve Tools &gt; One Curve and click the &quot;Set origin to spline start&quot;-button.

Select the curve, go into Edit Mode. Select the starting vertex. press Shift + S, and choose Cursor to Selected. Go into Object Mode. Press F3 (default search key) and type &quot;Set Origin&quot; and choose Origin to 3D Cursor.

In the 3D Viewport Header click the Snapping-button. (It is the icon next to the little magnet icon.) Choose Snap to Vertex. Then in the same header click Options and check the box next to Origins (uncheck it when you're done). Now hold Ctrl (or click the magnet icon) while moving the origin to snap it to the starting vertex.
